|MSGLEVEL= N | I|
If MSGLEVEL=I, SAS writes informative messages to the SAS log about index processing. In general, when a WHERE expression is executed for a data set with indexes, the following information appears in the SAS log:
if an index is not used but one exists that could optimize at least one condition in the WHERE expression, messages provide suggestions that describe what you can do to influence SAS to use the index. For example, a message could suggest sorting the data set into index order or to specify more buffers.
For informative messages about queries by an application to a SAS/SHARE server, MSGLEVEL=I must be set for the SAS session where the SAS/SHARE server is running. The messages are written to the SAS log for the SAS session that runs the SAS/SHARE server.
